After a very hefty pothole, I’ve noticed this cable loose - it is hanging freely in the lower grille of my Škoda Fabia (2025).

I can’t be sure it wasn’t loose before. As soon as I hit the pothole, I’ve had every error under the sun, including tyre pressure loss, no parking sensors, no road sign reading, stop start error, engine warning light etc.

Would this cable be responsible or what is a more plausible explanation?

Hello, welcome to the forum.

Must have been a hell of a bump. Practically a certainty that's the cause of your issue.

Check for where that should be plugged in to and refit.

If the front collision is giving an inactive symbol it might be that. It looks like it might have four wires so identifying their colours might help with what it goes to (I don't have a wiring diagram) brown is usually earth.

A 12v bttery in a too low state of charge for the computers can also cause all sorts of unexpected warning lights and messages even if the headlights seem bright enough and the engine starts easily (engine not starting needs the battery to be very low indeed). So check the state of charge of the battery just in case as you can have two (or more) issues/cause at once.

But of course the computer systems are very complex and intertwined so an issue in one can cause unexpected issues in others that's without the usual computer brain farts and errors and ommisions in the programs.

No connection should be that loose, but it's off - unless it's a connection not used in your trim level perhaps - so I would also check battery terminal and other electrial connections for tightness and security.

Hopefully someone else that knows or has access to a general wiring diagram may be along with more information.

Good luck let us know how you get on.

@deryanmoj did you find a home for that connecter, did reconnecting it clear the faults?
